Well I tried turning the nodes off and on again but I get a

able to
use gdb on it.
I appended the Driver sourcecode with my modifications.
I compile it with:
g++ -g -c -o ctest.o ctest.cpp\
-I/data/hiwi/tinyos/tinyos-2.x/tos/lib/tossim
g++ -g -o ctest ctest.o build/micaz/tossim.o build/micaz/sim.o\
build/micaz/c-support.o
"gdb ctest" produces:
(gdb) run

As I receive dbg output from my program's channel and Tossim dbg
here is
the complete output of ctest (without gdb) http://jawurek.net/
ProbCDUMP
At the end it appears if the sim_ticks var has overrun ?
Is this now a problem in my program for the nodes or some internal
TOSSIM error ?
Any help greatly appreciated.
It could be either, but it's more likely TOSSIM. I've never tested
trying to reset a simulation. I'll try to reproduce the bug and
hopefully the fix(es) will make their way into 2.0.2.
